Question: How To Repair A Boat Transom

Can a boat transom be repaired?

Repairing A Rotted Transom One method is to use a product like Git-Rot from BoatLIFE. This two-part liquid epoxy fills and restores the dry rot inside the wood using capillary action to penetrate it without drilling it full of holes. You can inject Git-Rot directly into the wood for more thorough penetration.

How do you repair a rotted transom?

Treat any wood left inside with CPES™. Cut new wood and treat with CPES™ and insert into transom, clamp/epoxy-glue it to the back of the transom, fill in all gaps with either the Fill-It™ epoxy filler or a putty-mix of the L&L Resin™, and then re-glass the inside. It’s real work.

How do you strengthen a boat transom?

Apply epoxy to the edges of the outer fiberglass skin of the transom and over the heads of the screws holding the skin to the plywood, and lay a strip of fiberglass cloth over the epoxy. Once the fiberglass has cured, repeat this step until four layers of fiberglass and epoxy have been applied.

Can you replace part of a boat transom?

While it is a pretty complicated job, replacing the transom core isn’t impossible. Transoms are usually replaced from inside the boat. This means removing all the internal structure, seats, and tanks, etc. Once you can get to the transom from the inside, it is time to cut away that inside layer of fiberglass.

How long do transoms last?

On to fabricating the replacement transom: Most, if not all wooden transoms in smaller boats are made of plywood. From the looks of the transom in this boat, I would estimate a typical transom will last about 20 years or so before they need to be replaced.

How much does it cost to replace a transom?

How much to fix a wet transom. Repairing a transom is a laborious exercise that can range from $3,000 to $10,000 depending on the vessel size construction and tradesmen used for the task.

How do you stop transom rot?

The best prevention for wood rot, is to remove all wood from a boat and use a material that will not rot. Finally, most boat manufacturers are moving this way with wood free transoms and wood free in the remainder of the boat. If a piece of wood is in and near water over a long period of time it will eventually rot.

How do you test a transom for rot?

Look for any signs of cracking around the transom. Look for any signs of transom bowing or deformation. Look for any signs of the motor mounting bolts and washers being pulled into the transom.

How does transom saver work?

The transom saver is a device that protects your boat’s transom from stress or eventual damage from forces exerted on it by the weight of the outboard while you are trailering it. The transom saver connects to the trailer’s rear cross, absorbing stress for the engine bracket and transom.

Do I need to reinforce my transom?

First and foremost, the transom of a fiberglass boat should not need being reinforced unless you are planning to attach a much larger motor than the boat is rated to handle. Doing that isn’t a good idea for many reasons, all of which involve your safety.

How thick should a boat transom be?

Outboard transoms are pretty much standardized at 1.5″. Most use two layers of 3/4″ ply, but a stronger method is three layers of 1/2″. Transoms are typically reinforced with knees, usually a couple at the rail and two or three on the bilge stringers, to transmit torsion loads to the bottom.

How many layers of fiberglass does a transom have?

You want each new layer extending far enough to catch more hull and more transom than the previous piece. Then you cover the whole transom with about 4 layers of 1708 to get your thickness.

How do you know if you have a bad transom?

Typically you will see the transom flexing under power, or flexing when applying pressure to the outboard (by hand). You may also see large stress cracks in the corners where the transom meets the sidewalls. For fiberglass you could take a core sample using a hole saw to see if the inner wood is wet and/or rotted.

What is a transom board?

Our Transom Board is 1 1/2″ thick 14 ply Marine grade. It is the same as used on new boats without the aluminum transom. Boards are sold in 2×4 sheets, simply remove your old transom trace the outline on the new transom and cut to size.

What is a transom shield on a boat?

Raybo3 the transom shield is considered the plates on the inside and outside of the transom that hold the drives on and connect it to the motor.

How do I know if my fiberglass boat is rotting?

On inboard and sterndrive boats, where transom flex is not as prevalent, a core sample can be taken from the inside of the transom to check for moisture or rot. Deck and stringer system problems go hand in hand. Soft spots on the deck are a sign of rotted and delaminated core materials.

What happens if transom is rotten?

Bad rot will lead to totally deteriorated wood and a lot of flex in the transom when the outdrive unit is under load. If you’re not experiencing that, then your transom overall is probably okay. You can probe with a piece of stiff wire around the screw holes and see if there is any severe softness.
